Bush was beaten in the race for Missouri’s 1st District by St. Louis prosecuting attorney Wesley Bell, who was backed by a major pro-Israel group.
The race was the second-most expensive House primary in U.S. history, according to the group AdImpact.
Bell attacked Bush’s service to the community suggesting that she was out of touch with her constituents throughout the monthslong race and highlighted the multiple investigations into her campaign finances.
Bush was the first member of Congress to call for a cease-fire between Israel and Hamas, nine days after Hamas’ Oct. 7 attack on Israel. Since then, she has continued to criticize the way Israel has handled their revenge.
She has also accused Israeli officials of committing genocide.
The United Democracy Project, a super PAC aligned with the American Israel Public Affairs Committee, poured more than $8 million into the contest to boost Bell’s campaign to replace Bush in the halls of Congress.
Before Bush, her fellow Squad counterpart, Bowman lost his primary election to an average candidate whose campaign was aided by outside funding.
The United Democracy Project spent more than $7 million in that race.
Others in the group still have a difficult race ahead this year. Rep. Ilhan Omar, D-Minn., faces a tough primary challenge from former Minneapolis City Council member Don Samuels next week.
